SPECIFICATION forming part of Letters Patent N 0. 736,294, dated August 1 1, 1903. Application filed MayJlO, 1902. Serial No. 106.833. (N model.)

To all whom it may concern:

Be it known that I, ROBERT OGLE, a citizen of the United States of America, residing at Pueblo, in the county of Pueblo and State of Colorado, have invented certain new and useful Improvements in Apparatusfor Condensing Smoke, Fumes, and Gases; and I do declare thefollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer-. ence being had to the accompanyingdrawings, and to the figures of reference marked there on, which form a part of this. specification.

My invention relates to improvements in means for condensing smoke, fumes,and gases from steam plants, furnaces, ore roasting plants, and smelters, whereby the carbon and solids are separated from the smoke,'fumes, &c., and discharged into the sewer or caught in receptacles when it is desired to save the carbon or recover the metallic or other values; and to this end Iprovide a condensing chamber or receptacle which is mounted in suitable proximity to the smoke stack or chimney and provided with filtering-diaphragms in-' terposed between the inlet from the stack to the chamber below the stack-damper and the outlet from the chamber to the stack above the damper. By the operation of my improved apparatus most of the gases are united with the water employed in the condensing operation. Provision is also made for the introduction of steam-jets and sprays of hot and cold water to the tank, all of which will be fully understood by reference to the accompanying drawings, in which is illustrated an embodiment thereof.

In the drawings, Figure 1 is a vertical longitudinal section taken through the condens furnace, boiler, and stack. Fig.2 is a plan View of the same, parts being shown in section on the line a: at, Fig. 1. Fig. 3 is a section taken on theline y'y, Fig. 1, looking downward. Fig. 4. is a fragmentary detail View of one of the screen-netting diaphragms shown on an enlarged scale.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the boiler,

and 4: the stack. Suitably mounted adjacent the stack is a condensing-chamber 6,. having a trapped outlet 7 at the bottom.. The damper 8 of the stack is closed when my improved apparatus is in use. Leading from the stack below the damper is an upwardly-inclined conduit 9, which projects intolhe chamber 6 below a horizontal diaphragm 10, composed of wire-netting located in the lower part of the chamber. the drawings, is composed of two layers of coarse -mesh netting, the wires of the two mesh members being staggered to divide the openings. In practice it has been found that wire-netting having eight meshes or openings to the square inch will give satisfactory results. As shown in the drawings, the chamber 6 is largest at the bottom and gradually tapers toward the top, where it is smallest. Its upper extremity projects into an opening formed in the stack above the damper. The walls of the chamber are curved sufficiently from the bottom upward to allow the upper extremity of the chamber to enter the stack, as aforesaid. This construction presents no angles to obstruct the draft. Suitably mounted on the wall of the tank above the diaextremity of the conduit 9 is a funnel-shaped receiver. 12, into which the products of combustion are discharged after passing through the diaphragm. The function of this receiver is to temporarily suspend the products of combustion or the smoke, fumes, and gases as they issue from the conduit 9, whereby condensation is facilitated. Above the receiver, located near the top of the condensingchamber, is another diaphragm, which is designated in thedrawings. This diaphragm is also composed of wire-netting, preferably somewhat coarser than that employed in making the lower diaphragm. In practice two six-mesh membersarranged in staggered relation have given satisfactory results.

Leading from a cold-water pipe 16'are two branch pipes 17 and 18, which extend into the condensing-chamber and terminate in spraynozzles 17 and 18, respectively. 'One of This diaphragm, as shown in 'phragm 10 and directly opposite the discharge ber between the two diaphragms.

Leading from the boiler and connected therewith at a point above the water-level is a steam-pipe 19, provided with two jet branches and 21, one located in the conduit 9 and the other entering the chamber between the two diaphragms and, as shown in the drawings, nearer the upper diaphragm. Leading from the boiler and connected therewith at a point below the water-level is a hot-water pipe 22, which enters the condensing-cham- The discharge of water through this pipe is controlled by a valve 23. The function of the pipe is to discharge hot water into the condensing-chamber when a fire is first made in the furnace, the object being to condense black smoke, which usually issues from the stack when the fire is started or when the fuel is renewed. This hot-water jet is only temporarily employed, and the valve 23 may be closed after the fuel has reached the proper stage of condensation.

When the apparatus is in use, the stack damper 8 is closed, and the products of combustion containing the smoke, fumes, and

'gases from the furnace are driven into the condensing-chamber,where they are acted on by the water-sprays and steam-jets. The impurities, as the carbon (which is the chief element of black smoke) and the other elements, which under ordinary circumstances render the escape from furnace-stacks obnoxious, are

condensed and fall to the bottom of the chamber, whence they are carried 01f with the water through the trapped outlet 7 and discharged into the sewer or to any suitable receptacle in case it is desired to recover the carbon. The gases or fumes from smelters and ore-roasting furnaces will unite with the water and may be discharged into the sewer. If, however, they contain mineral values, the

water may be drawn off into suitable receptacles and the values precipitated at will. The mesh diaphragms 10 and 15 ofier an obstruction to the products of combustion in the ,chamber 6 or retard their progress therethrough sufficiently to make it practicable to condense the carbon and other impurities by the action of the water and steam, as heretofore explained.

Having thus described my invention, what I claim is-- 1. In an apparatus for condensing smoke,

fumes and gases, the combination with a stack 2. The combination with a stack, 'of a condensing-chamber arranged adjacent the stack and a damper therein, said chamber being largest at the bottom and tapering toward the top where it communicates with the stack above the damper, the walls of the chamber being curved and devoid of angles above the bottom, one or more mesh diaphragms located therein, means for introducing the prodnets of combustion from the stack below the damper into the chamber below the lower diaphragm, and means for introducing jets of steam and sprays of water into the chamber, substantially as described.
